Standard for installation and acceptance of mechanical
equipment in metallurgical mine
1 General provisions
1.0.1 This standard is formulated to ensure the quality of installation of mining
machinery and equipment.
1.0.2 This standard applies to the installation and quality acceptance of mechanical
equipment and mining electrical equipment for new, rebuilt, expanded ferrous mines
such as mining, long-distance continuous transport, stacking and reclaiming, crushing
and sieving, grinding and classifying, separation, dewatering, etc.
1.0.3 The requirements for installation quality in engineering technical documents,
contracts, etc. for the installation of mining machinery and equipment shall not be lower
than the requirements of this standard.
1.0.4 In addition to complying with the requirements of this standard, the installation
and quality acceptance of mining machinery and equipment projects shall also comply
with the requirements of the relevant national standards in force.
2 Terms
2.0.1 Magnetic separation
A separation method that uses the magnetic difference of mineral materials to achieve
separation.
2.0.2 Flotation
A separation method, that uses the buoyancy of bubbles to separate materials from
slurry, based on the differences in physical and chemical properties of granular mineral
materials.
2.0.3 Gravity separation
A separation method, that uses different densities of granular mineral materials to show
different movement speeds and trajectories, under the action of air, water, emulsion and
other media and mechanical forces.
2.0.4 Tubular belt conveyor
Also known as tube-type belt conveyor and round tube belt conveyor. The receiving
and discharging sections are the same as those of the belt conveyor. The cross section
of the transport section is a closed hexagonal roller, which forces the belt to form a
nearly circular shape, so that the material can be transported in a closed tubular belt
without pollution or leakage. At the same time, horizontal and vertical turns can be
realized; the upper and lower belts can transport materials in both directions at the same
time.
3 Basic requirements
3.1 Installation
3.1.1 The construction site shall have corresponding construction technical standards,
a sound quality management system, quality control and inspection system, as well as
technical documents such as construction program, construction plan, operation design
approved by the technical person in charge.
3.1.2 Design changes shall be accompanied by a design change notice or technical
verification signature certificate.
3.1.3 Construction quality inspection and acceptance shall use measuring instruments
that have been verified and calibrated.
3.1.4 Special operations personnel must pass the examination and obtain a certificate
of qualification; perform construction work within the scope of the qualified
examination items and their approval.
3.1.5 Mining equipment installation projects shall comply with the following
requirements:
1 Handover inspection shall be carried out between related disciplines and records
shall be formed;
2 After each process is completed, it shall be checked and recorded. The next process
shall not be carried out without inspection and approval of the previous process.
3.1.6 The construction organization shall notify the relevant organizations of the
acceptance of the secondary grouting of equipment and other concealed works before
concealment; form acceptance documents.
3.2 Quality acceptance
3.2.1 Construction quality acceptance shall be carried out according to sub-projects,
division projects, unit projects on the premise that the construction organization has
1 The quality of all division projects included in the sub-project has been accepted;
2 Quality control records shall be complete;
3 The equipment unit has passed the no-load test run.
3.2.4 The acceptance of the quality of the unit project shall meet the following
requirements:
1 The quality of all division projects included in the unit project has been accepted;
2 Quality control records shall be complete;
3 The equipment has passed the no-load linkage test run;
4 The visual quality has been accepted.
3.2.5 The visual quality inspection items of unit project shall comply with the following
provisions:
1 Bolts, nuts, and washers shall be fully configured according to the design. After
tightening, the bolts shall be exposed from the nuts or flush with the nuts; the
exposed threads shall be free of damage; the bolt insertion direction shall be
consistent except for structural reasons;
2 The seal shall not leak oil, water or air;
3 The pipeline laying layout shall be reasonable, neatly arranged, beautiful;
4 The layer thickness of the sound insulation and thermal insulation materials shall
be uniform; the binding shall be firm; the surface shall be flat;
5 The paint coating shall be uniform, without holiday, peeling, obvious wrinkles and
bubbles; the color shall be basically consi...
